JONATHAN BARTLETT, OF EPPING, AND GEORGE B. \VIGGIN, OF SOUTH NEWMARKET, NEXV HAMPSHIRE, ASSIGNORS OF ONE-HALF TO JOHN W. HOARD, OFPROVIDENCE, RHODE ISLAND.

SEWING-'IVIACHINE.

SPECIFICATION forming part of Letters Patent No. 399,818, dated March19, 1889.

Original application filed July 28, 1887, Serial No. 245,561 Divided andthis application filed May 8, 1888. Serial No. 272,747- (No model.)

To ctZZ whom, it nuty concern:

Be it known that we, JONATHAN BARTLETT, of Epping, and GEORGE B.VVIGGIN, of South New Market, in the county of Rockingham and State ofNew Hampshire, have invented certain new and useful Improvements inSewing-Machines; and we do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters ofreference marked thereomwhich form a part of this specification.

Our invention relates to sewing-machines generally, but moreparticularly to the class of waxed-thread machines adapted for sewingshoes or other articles made from leather or other kindred material, buthas more especial reference to the construction of the work-supportingdevice, or what is usually called the horn, and to the construction andaction of parts adjacent thereto.

In the accompanying drawings, Figure 1 is a side elevation of the hornand thread-looper; Fig. 2, a front View of the same, and Fig. 3 a planview of the angle-piece on top of the horn.

Our improved horn or work-rest is shown in Figs. 1, 2, and 3 in itsrelation to adjacent parts. The horn has on its top a loosely-pivotedright-angled tongue or lip, 1, whose up per edge is adapted to projectinto a slit cut in the sole of a shoe or other piece of leather, and asmall notch, 2, in the base of this rightangled piece permits the pieceto have a slight swinging movement on its center or pivot 3, which isrestricted by a fixed pin, 4:, in the horn. This lateral play or swingallows the tongue 1 to accommodate itself to the curves or sinuositiesof the sole when sewing, and especially at its hollow or shank part.\Vhen sewing around certain convex partssuch as the heel of the boot orshoethe position of the tongue (see Fig. is rigid, inasmuch as one sideof the slot 2 then bears continually against this pin, the tongue beingturned slightly to one side, and without this turning the curves wouldnot be so truly and readily rounded. The horn at its upper end rests 011and forms an arch with an upright portion or plate, 5.

Vith this form of horn and its swinging tongue 1 we prefer to use thecrank-shaped and tubular thread looper or carrier o and post nipinion n,and supporting-sleeve a, substantially as shown. The pinion 91 engageswith a concave instead of with a convex rack; but these looping devicesform the subj cot-matter of an independent application, Serial No.272,746, filed May 3, 1888.

Referring now to the drawings, which show our improved form of horn inits relation to our preferred looping devices, the position of the partsis shown at that stage of the sewing after the needle has just caughtthe thread and is carrying it through the sole of the shoe. The arrownear the lower part of Fig. 1 shows the direction or route of the threadfrom the wax-pot, which, as usual, is located below the machine, and theupper arrow shows the direction of the needle-feed movement.

Our machine can be used for sewing almost any material; but it is moreparticularly adapted for sewing shoes, either turned or welted, thenarrow edge afforded by the horizontal top T of the horn beingparticularly adapted for welted goods.

This application beingone of the divisions of our original applicationfiled July 28, 1887, Serial No. 245,561, we do not herein claim anythingclaimed either in that application or in either of the other divisionapplications, Nos. 272,745 and 272,716, both filed May 3, 1888 Theimproved horn and rest described, the rest being a pivoted angled piece,1, having an opening at the rear of its base and the horn having a fixedpin projecting into such opening, which opening is larger than the bodyof the pin and serving to limit in both directions the swingingmovements of such rest.
